Thanks for your answer, but in your case, your db is external, so REST
maybe the right way.
in mine, the db is embedded in cocoon, and the xquery are more
complicated (call to external function in java using JTS...) and the
xqueries needs parameters setted in the xml post...
That's why i need a xqueryTransformer...

Don't know (the particulars of your application for quick proof-of-concept
vs. production performance). I suspect the depth of your research into the
problem makes you the authority in this area. Sorry not to be of more help!

a custon generator is a better solution than use the XQueryTransformer +
eXist module extension on JTS api ?

Sébastien,
I have not explored such a model before, so I can't be
of more help. A custom generator may be an option, as well,
though I know you were looking for a quick solution.
Love to hear about your ultimate solution.

At first, i intend to use JTS in XQuery function which could call java
function, implemented with the JTS API.
But performance could be a problem...
In fact i'd like to do spatial query on XML database....
Cocoon handles XML post request, then requests the eXists database by
XQuery (extension with API JTS), and then format the XML return...
Any opinion about kind of architecture ??
(It is just a proof of concept, not intended to be on production...)

Sorry for misunderstanding. The XQueryTransformer code was posted by Ben
Anderson
<http://www.mail-archive.com/users@cocoon.apache.org/msg24913.html>.
The xml in the POST is no problem, but the JTS suggests the possibility of a
flow solution (with the org.xmldb.api.DatabaseManager and
org.xmldb.api.base.Collection interfaces).
